Letters Patent No. 96,7 49, dated November 9, 1869.

IMPROVED CAR-COUPLING.

The Schedule referred to in these LettersPatent and making part of thesame To all whom it may concern.-

Be it known that I, DAVID -.G. WHrrMonn, of Bridgewater, in the county.of Rockingham, and in the State of Virginia, have invented certain newand useful Improvements in Gar-Couplings; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanyingdrawings, and to the'letters of referencemarked thereon, making a part of this specification.

The nature of my invention consists in the construction and generalarrangement of a self-coupling car-coupling, which can be locked, so asnot to come uncoupled of itself.

In order to enable others skilled in the art to which my inventionappertains, to make and use the-same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in whichFigure lis a longitudinal vertical section, and

Figure 2, a plan view of my invention,

A A represent the bumpers or draw-heads, at a suit able point in each ofwhich is pivoted a cross-shaft, B.

To the shaft B is secured the bar 0, which answers the purpose of theordinary coupling-link, said bar extending forward through the -mouth ofthe draw-head, and is at its outer end, on the under side, providedwith, or rather shaped, in the form of a hook, a, so that when insertedinto the opposite draw-head, this hook will catch on the inner loweredge of said draw-head.

Both of the draw-heads A A being provided with a bar or coupling-link,O, the cars become coupled by two suchbars, they being placed a littleto one side, so as to admit of both bars passing through the mouth orentrance of the draw-heads. v

The lower edges of said entrances are bevelled on the outside, and theouter ends of the bars. 0 G are also bevelled, so that when the cars arebrought together, they will couple themselves.

At the front end of the draw-head A, resting upon the bottom, betweensuitable guides .in the sides, is a bar, D, which, at one end, isprovided with a vertical rod, E, that extends upward through the top ofthe draw-head, and is intended to be situated nearthe brake-wheel on theplatform, so that the brakeman can readily operate the same, by means ofthe handle G, attached to its upper end.

By raising the rod E, the bar D will be moved upward in its guides, boththe bars or coupling-links O O lifted up, and, consequently, the carsuncoupled.

It will be seen that it is not necessaryto operate the bars D D in bothdraw-heads; either one will suffice to uncouple the cars, as either onewill-raise both coupling-links.

To the rod E, and extending toward the rear, is se cured a wing, H, thelower edge of which is, when the bar D rests upon the bottom ofthe'draw-head, ashort distance below the upper edge of. the coupling-bar0, so that by merely turning the rod E, which might sometimesunintentionally be done, the wing H will not be brought on top of saidbar.

By raising the rod E slightly, and then turning it, the wing H isbrought across both of the couplingbars 0 O, and then reaching nearlyup" to the top of the draw-head, it prevents the cars from uncoupling.

The upper side of the coupling-bar'O is, near the front end, notched, orprovided with a shoulder, 71, so that when the wing H is brought acrossthe bars 0 O, as above described, it will slide over and be held by thisshoulder, and by this means the coupling is prevented from accidentallyunlocking itself.

To unlock the coupling, it is only necessary to raise the rod Esuiiicient to allow the wing H to clear the shoulder b, when it canreadily be turned back again to its first position, away from thecoupling-bar 0.

Having thus fully described my invention,

'What I claim as new, and desire to secure by Letters Patent, is

l The wing H, secured tothe rod E, and operating substantially in themanner and for the purposes herein set forth. t

2. The combination of the bar D, rod E, handle G, and wing H, allconstructed as described, and operating substantially as and for thepurposes herein set forth.

3. The combination and arrangement of the drawhead A, rock-shaft B,coupling-bar 0, bar D, rod E, and wing H, all constructed as described,and operating substantially in the manner and for the purposes hereinset forth.

In testimony that I claim the foregoing,I have hereunto set niy hand,this 13th day of October, 1869.
